Delete first column of a numpy array

Question

I have the following np.array():

[[55.3  1.   2.   2.   2.   2. ]
 [55.5  1.   2.   0.   2.   2. ]
 [54.9  2.   2.   2.   2.   2. ]
 [47.9  2.   2.   2.   0.   0. ]
 [57.   1.   2.   2.   0.   2. ]
 [56.6  1.   2.   2.   2.   2. ]
 [54.7  1.   2.   2.   2.   nan]
 [51.4  2.   2.   2.   2.   2. ]
 [55.3  2.   2.   2.   2.   nan]]

And I would Like to get the following one :

[[1.   2.   2.   2.   2. ]
 [1.   2.   0.   2.   2. ]
 [2.   2.   2.   2.   2. ]
 [2.   2.   2.   0.   0. ]
 [1.   2.   2.   0.   2. ]
 [1.   2.   2.   2.   2. ]
 [1.   2.   2.   2.   nan]
 [2.   2.   2.   2.   2. ]
 [2.   2.   2.   2.   nan]]

I did try :

MyArray[1:]#But this delete the first line

np.delete(MyArray, 0, 1) #Where I don't understand the output
[[ 2.  2.  2.  2.  2.]
 [ 1.  2.  2.  2.  2.]
 [ 1.  2.  0.  2.  2.]
 [ 2.  2.  2.  2.  2.]
 [ 2.  2.  2.  0.  0.]
 [ 1.  2.  2.  0.  2.]
 [ 1.  2.  2.  2.  2.]
 [ 1.  2.  2.  2. nan]
 [ 2.  2.  2.  2.  2.]
 [ 2.  2.  2.  2. nan]]

Answer 1

You could try: new_array = [i[1:] for i in MyArray]

Answer 2

Try MyArray[:,1:] I think you can get rid of column 0 with this

Answer 3

It should be straight forward with

new_array = MyArray[:, 1:]
